Magnetogastrography
Magnetogastrography
Magnetogastrography (pronounced: mag-net-o-gas-tro-gra-phy) is a non-invasive diagnostic technique used to measure the magnetic field produced by the electrical activity of the stomach.
Etymology
The term "Magnetogastrography" is derived from three Greek words: "magnētis" meaning magnet, "gastro" meaning stomach, and "graphia" meaning writing or recording.
Procedure
In a Magnetogastrography procedure, a patient is asked to ingest a small amount of a magnetically active substance. Sensors placed on the skin above the stomach then measure the magnetic field produced by the stomach's electrical activity. This data is then used to create a visual map of the stomach's activity, which can help diagnose various gastrointestinal disorders.
Related Terms
- Gastroenterology: The branch of medicine focused on the digestive system and its disorders.
- Electrogastrography: A procedure similar to magnetogastrography, but it measures the electrical activity of the stomach using electrodes placed on the skin.
- Gastrointestinal tract: The system of organs within the human body that takes in food, digests it to extract and absorb energy and nutrients, and expels the remaining waste as feces.
- Magnetic Field: A field of force produced by electric charge in motion.
Applications
Magnetogastrography is primarily used to diagnose disorders of the stomach's electrical activity, such as gastroparesis, a condition in which the stomach's muscles are impaired and cannot move food properly. It can also be used to monitor the effectiveness of treatments for these disorders.
